660 with significant screen tearing problems

[Glisen_man]

So i recently bought an 660(for my new gaming PC) and im having major issues with Screen tearing

Im using a 60hz 1080p monitor and obviously i would expect screen tearing when it goes above 60 fps,but it seems Really bad,when i limit the FPS rate to say 59-60 i still get noticeable screentear quite often.


Running msi afterburner while playing games also gives me somewhat unexpected results,when a game is running at say 60fps solid the Frametime/ms is at around 23-30ms per frame a lot of the time,shouldnt this be at 16ms if the game is at 60fps?

the discrepancys are similar at other frame rates aswell,as FPS goes up the frame time/ms doesnt correspond with what it should it be,its always longer


anyone got any idea wtf is goin on?

Im running the latest drivers

screen tearing can still happen bellow the monitors refresh rate, its a property of the monitors display buffer being updated when a frame is only partially updated already.

best fix is to enable vsync and forcing double or triple buffering.

i started to force triple buffering, vsync and an fps cap of 59 to all my games and besides the tearing vanishing i have no difference in my input latency that is massively noticeable if noticeable at all.

i also change my flip queue (ati equivalent of frames to render ahead) to 1 which also helps reduce input latency.

so i did a test with the setings via the nvidia control panel

1st up i tried CS:GO,constant 60fps,no screen tearing framerate/ms times as expected (16ms constant)

Then Anno 2070,no screen tearing, fps was between at 55-60 most of the time,but there was a lot of stutter and and acording to afterburner when at 60fps the frametime/ms was 30ms with jumps higher than that as the fps dropped in the 45-60fps range


Tried farcry 3 seemd to have no screen tearing,seemed to stutter quite a lot tho. Afterburner said the fps was between 45-60,but the frametime/ms was always at 25ms+ when at 60fps and obv higher as the fps dropped

So what exactly is goin on here? the time it takes to render frames seems incosistant with the 'apprant' framerates
